Zero Liquid Discharge in Indian Industries: Nagda & Beyond
Introduction
In the face of increasing water scarcity and stringent environmental regulations, Indian industries are taking bold steps towards sustainability. Among these initiatives, Zero Liquid Discharge (ZLD) has emerged as a transformative practice in water-intensive sectors like textiles and food processing. This blog delves into the advancements in ZLD, particularly focusing on developments in Nagda, and how Indian industries are paving the way for a more sustainable future.
The Significance of Zero Liquid Discharge
Zero Liquid Discharge refers to the process of eliminating liquid waste by recovering and reusing all wastewater generated in industrial operations. This system aligns with global sustainability trends and addresses India’s pressing water scarcity challenges. As the textile industry significantly contributes to water usage and pollution, implementing ZLD systems is essential for ensuring regulatory compliance and enhancing operational efficiency.
Key Developments in ZLD Implementation
1. Grasim Industries: A Benchmark in Nagda
Grasim Industries has set a benchmark in Nagda by achieving a water recovery rate of 98% in its Viscose Staple Fiber (VSF) production facilities through a partnership with Veolia. This pioneering effort demonstrates the viability of advanced water management technologies supporting both sustainability and economic growth.
2. Market Growth Projections
Market research indicates that the Zero Liquid Discharge systems market in India is projected to grow from USD 1.14 billion in 2024 to USD 1.84 billion by 2030, driven by stricter environmental regulations and the need for cost-effective wastewater management solutions. As industries adopt ZLD technologies, this trend signals a shift towards sustainable industrial practices in India.

3. Emerging Technologies
Innovative technologies like the Mechanical Vapour Recompression Evaporator (MVRE) developed by Chemin Enviro Systems are driving down ZLD operational costs. With costs reduced from Rs 1,100 to Rs 600-650 per kiloliter, industries can achieve substantial annual savings while expediting their return on capital investments.
Adoption Trends and Market Implications
1. Regulatory Landscape and Industry Response
As government mandates become stricter in high-water-use industries, demand for ZLD solutions is expected to surge. For instance, ethanol production plants must implement ZLD to prevent wastewater discharge, accelerating the adoption of these technologies across sectors.
2. Market Segmentation Insights
The distribution of ZLD implementations across sectors reveals:
Chemical Industry : 40%
Textile Industry : 25%
Food & Beverage : 15%
Pharmaceuticals : 10%
Power : 10%
